What kind of attorney would you need for a medical kidnap case?

No sucha thang in them lawbooks, babe. There is a Parental Kidnapping Prevention Act (PKPA), but there is no MKPA. Kidnapping by a non-parent is kidnapping, plain and simple, and it's a crime. So, you need a criminal prosecuting attorney. But I think you are asking about urban myth internet nonsense metaphor unclear thinking. Get an entertainment attorney who specializes in drama.

A good one.
